Claims; (Cl. 139--199) This invention relates to improvements in shuttles more particularly of the type used on narrow ware looms and it is the general object of the invention to provide a shuttle having a simple form of combined weft quill bearing and quill flange guard.

Shuttles of the narrow ware type are ordinarily made with a weft compartment in which is rotatably mounted a quill from which weft leads through various tension devices and then out a delivery eye in the arched or bowed side of the shuttle. In the past it has been customary to mount the quill on a bearing pin 'or rod extending across the compartment and having one end entering the shuttle and having the other end frictionally held to the body of the shuttle.

The shuttles are driven positively by a rack and pinion. mechanism which moves them through the warp sheds from one shuttle block to another. vTo prevent the quill flanges from engaging and breaking the warp threads it has been customary in the past to provide the shuttle with a small wire guard extending across the base of the shuttle and so located as to prevent the warp threads from engaging the quill. This guard is usually located at a considerable distance from the quill to permit the latter to be removed from the shuttle when depleted of weft. It isdesirable that the guard be closer to the quill flanges than heretofore without interfering with removal of the quill.

It is an important object of the present invention to combine the quill bearing and guard in a single member extending across the weft compartment and having a bearing part for the quill and having another quill flange guard part lying outside the outline of the shuttle. The guard is spaced from the bearing a sufficient distance to make room for the quill and extends suiiiciently above the shuttle to prevent the warp from engaging the quill. The guard is removed with the bearing and thus does not interfere with removal of the quill. The guard can be made shorter than usual and be located directly over the quill flanges.

It is usual practice in narrow ware mills for the weaver to wind the quills on a so-called quiller mounted either on or near the loom. The usual procedure is for the weaver to remove a depleted quill and its bearing pin from a shuttle, .remove the bearing, fit the quill to a bearing on the, quiller, and then lower the quill against the winding drum. After the quill is wound it is removed from the quiller bearing, fitted to the pin bearing, and then replaced in the shuttle.

It is another object of the invention to simplify this procedure by combining the bearing and guard in a member which can be slipped out of the shuttle and fitted directly to the quiller without removing the quill from the bearing.

As set forth hereinafter two forms of the invention are shown, the preferred form having aligned free bearing ends connected to each end of the guard by cross ends or elements which fit into supports on the shuttle. The modified form is made U-shaped and has one of its sides made as a bearing extending entirely through the quill and has the other side made as the guard.

With these and other objects in'view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts hereinafter described and set forth. I

In the accompanying drawings, wherein two forms of the invention are set forth,

Fig. 11 is a view similar to Fig. 7 but showing a modification.

Referring particularly to Fig. 1, the lay ll) 0 a narrowwarelo om is shown as provided with two shuttle blocks II and I2. It is to be under; stood that narrow ware looms are ordinarily made with a large number of these blocks er: I

ranged side by side along the lay and separated to provide spaces for reeds two of which are shown herein at Hi and I4. A rack I is reciprocated lengthwise of the lay by well-known mechanism not shown herein and drives pinions l6 and H rotatably mounted on the shuttle blocks II and I2, respectively.

The shuttles S mesh on their under sides with the pinions and slide along arcuate grooves or guides in the shuttle blocks. In the present instance each block has a groove 2|! extending downwardly to the right and crossing another groove 2| extending downwardly and to the left. The shuttle in block H, for instance, will be moved by its pinion [6 to the left down the groove 2|, across the space for reed l3, and then pinion I! will move it up along groove 20 of block I2. When the pinions reverse the shuttles travel in the opposite direction and will return to the positions shown in Fig. 1.

The warp of the loom has top and bottom sheds WI and W2 leading to the fabric F, see Fig. 4. In Fig. 1 these sheds are represented by vertically spaced horizontal series of dots. The shuttles pass through the sheds, moving to the left to lay one pick and then moving to the right to lay the next pick.

The weft thread T is wound on the barrel 25 of a weft quill 26 having a bore 21 therethrough and having end flanges 28 and 29. The weft thread T is led forwardly from the quill through a tension eye 30, then to the right to another tension eye 3|, then across the thread compartment C in which the quill is located to another eye 32, and thence through the delivery eye 33 located in the bow 34 of the shuttle. The eyes 3032 are resiliently mounted by springs not shown herein but well understood. A tension pad 35 for engagement with the quill may be provided as usual.

The matter thus far described is of well-known construction and of itself forms no part of the present invention.

The preferred form of the invention provides a member 45 which is a combined quill bearing and quill flange guard. As shown more particularly in Fig. 5 this member 40 may conveniently be formed of a single piece of bent wire having right and left free ends forming coaxial quill bearings 4| and 42 bent toward each other. These ends are connected by cross or end elements 43 and 44, respectively, to a'quill flange guard 45. The bore 2! of the quill receives the free end bearings 4| and 42 which hold the quill spaced at such a distance from the guard 45 that the quill can rotate freely. The guard extends over the flanges 28 and 29 of the quill as shown in Fig. 2.

The quill compartment C in the shuttle has right and left side walls 41 and 48 into which are set supports 49 and 50, respectively. These supports are secured into the shuttle body and have grooves 5| to receive the cross or end ele: ments 43 and 44 of the member 4|! and hold the latter frictionally in position with the guard extending above the outline of the shuttle, see Fig. 4-. The free bearing ends 4| and 42 are located within the outline of the shuttle.

As shown in Fig. 2, the guard 45 extends across compartment C and over the quill flangesand prevents the latter from engaging the top warp shed WI as the shuttle passes from one block to another. The member 40 therefore constitutes a single unitary device which provides a bearing for the quill, means for frictionally holding it in the shuttle, and a flange guard 45 located closer to the quill than has been possible in previous constructions.

As already stated it is common practice for weavers operating narrow ware looms to wind their own quills. This operation is performed on a form of winder, usually called a quiller, mounted either on the loomside or in some position near the loom. As shown in Fig. 6 the quiller has a frame 55 in which is rotatable a shaft 56 to which is secured a drum 5!. The latter is fast with a pulley 58 turned by a belt 59 driven from any convenient source of power.

An arm 60 extends upwardly from frame 55 and has a rod 6| fixed therein by a set screw 62. Mounted fOr angular movement on this rod is a quill carrier 65 which as shown in Fig. 7 comprises a support or casting 66 formed with bearings 61 to fit the rod 6|. Secured at 68 to the support 66 is a second rod 69 extending at the right, see Fig. '7, and having a second support or casting 10 secured thereto by set screw 1|.

Support 66 has an arm 12 provided with a slot 73 the plane of which extends toward the axis of rod 6|. Similarly, the support 10 has an arm 14 having another slot 15 similar to slot 13.

When the quill and its combined bearing and guard member have been removed from the shuttle upon depletion of weft the cross or end elements 43 and 44 and the rear parts of the free ends 4| and 42 adjacent to the elements are fitted into the slots 13 and 15. Support 10 is set on rod 69 in such position as to cause the cross elements 43 and 44 to be frictionally held in the supports 66 and 70. The thread T is then led from a source of supply around guide roll 76 and through a traversing reed TI to the barrel 25 of the quill. The quiller is then started in rotation and winds thread T on the barrel be tween-the flanges 28 and 29. After the winding operation is completed the quill and the member 40 are removed from the quiller and are ready for insertion into the shuttle. This operation is performed without removing the quill from the free bearing ends 4| and 42, and the member 40 is so made that it not only serves the purpose of supporting the quill in the shuttle, but also supports it in the winding mechanism. The quill is permanently mounted on member 40, but the latter is so made that it can be detached from the quill, if desired, by bending to the dotted line position shown in Fig. 5.

The modified form of the invention, shown in Figs. 8 to 11, provides a U-shaped member 80, made preferably of bent wire, having a quill bearing 8| which extends across the compartment C in the shuttle S and through the whole length of the quill. The free end or support element 82 of this bearing may be pointed or otherwise formed to enter a recess 83 in a plate 84 secured by screws 85 to the shuttle Si at the left side of the space C. I

That end of the bearing 8| remote from its free end 82 is bent transversely to form a cross or end element 86 for reception by a grooved support 81 similar to thefriction supports 49 and 50. The member 80 then bends to the left from element 86 and extends across compartment C more or less parallel to the bearing 8| to provide a quill flange guard 90. The free end or support element 9| of the guard 90 enters a hole 92 in the upper part of plate 84, as shown more particularly in Fig. 8.

When the member 80 and its quill are in the shuttle as shown in Fig. 8 the quill is rotatable on the bearing 8| and the free ends 82 and 9| are supported by the plate 84, and the guard 90 extending outside the outline of the shuttle and over the quill flanges. As the shuttle SI moves between the warp sheds the guard 90 serves the same purpose as does the guard 45 and keeps the Warp threads from engaging the flanges of the quill.

When the quill shown in Fig. 8 is depleted of Weft the weaver will grasp the right hand side of the member 88 and lift it. This will move the free end 82 out of the recess 83 and will permit right hand movement to remove the free end 9| from hole 92. The quill and member 8!] can then be taken to the quiller which may be similar to that already described except that the support 58 is replaced by another support 95. The latter has an arm 96 provided with a recess 91 for free end 82 of bearing 8| similar to the recess 83 in plate 84. Casting 95 also has a hole 98 for free end 9i similar to hole 92. When free end 9! has been inserted into hole 98 the cross element 86 is forced into slot M of casting 18 and the winding operation carried on as already described in connection with the preferred form. After the quill is wound it is removed from the winder along with member 88 and is ready for reinsertion into shuttle SI.

From the foregoing it will be seen that in both forms of the invention the combined bearing and guard is formed of a single member, preferably wire, bent on itself and providing bearing means for the quill and also guard means for the quill flanges. Both forms of the invention are of such form that the quill can be held either in a shuttle or in a winding machine Without being removed from its bearing. The quill and its bearing and guard member of either form constitut a quill unit which can be applied either to a shuttle or a quiller. The resilience of the wire serves to hold it in the shuttle and also the quiller. In both forms the guard serves also as a bail or hand hold by which the quill may be readily manipulated.

Having thus described the invention it will be seen that changes and modifications of the foregoing specific disclosure may be made without departing from the spirit and scope of the invention.
